ABSTRACT:
A novel mixing apparatus for pulverent material, slurries and paste like material is disclosed. The apparatus is especially suitable for mixing cement and sand into mortar. The mixing apparatus comprises a casing having a cylindrical inner surface and a screw member mounted within the casing for rotation relative thereto about an axis which is coaxial with the axis of the inner surface, characterized in that the screw member includes a plurality of flights which at least approximate portions of a helical screw but which are arranged such that the tailing portion of one flight overlaps, as viewed axially, the leading portion of the next succeeding downstream flight. The overlapping flights promote turbulence in the flow which ensures good mixing.
